This might not be the best place for this question, but I'm at a loss of where to go with this. I just put together my temperature regulation unit for the HLT on the RIMS system I'm building. I ran into a snag when testing it. If someone knows a better forum for electrical questions such as this, please help a poor soul out
I put together a PID temp controller and solid state relay to control a 115v water heater element. The PID can run off 110v, so I'm tying it into the same circuit (as the manual suggests).
The initial tests were going just fine - for about 5 minutes - and then my 15amp breaker would pop. After about 5 repeats, I move the unit to a unoccupied 20amp circut and things were going smoothly. Until about 20 minutes in I heard something pop. I'm beginning to suspect that it was the SSR, since it no longer seems to want to carry a load and all other connections are kosher. It'll gen ~110V, but won't carry a load. Happens all the time too - even when there isn't a signal on the DC side.
So, I think I didn't follow the diagram that came with the PID correctly. Maybe somehow I was overloading something with incorrect wiring.
Here's the diagram that came with the PID:
And here's basically what I did. The boxes above the AC line are junction connector blocks:
Did I misunderstand something from the product diagram, or did I just get a bad SSR?
